After lncRNA NORAD was overexpressed in OS cell lines Saos-2 and 143B via transfection with NORAD siRNA, the cell proliferative and invasive abilities and in vivo tumor growth were all markedly suppressed [30], which was tallied with our finding that BMSC-EVs carried NORAD into OS cells to accelerate OS cell growth. Here, NORAD is linked to neoplasm.
